CAN-BODY-IVIAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 436,792, dated September 23, 1890.

Application filed March 22, 1889.

To @ZZ whom, t may concern.'

Be it known that I, PETER JORDAN, a citizen of the Unit-ed States, residing at Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Can-Body-Making Machines, ot which the following is a specification.

My invention relates to machines for making can-bodies.

The object of my invention is to provide a machine which will automatically feed the l blank, form it into a can-body, and interlock and fold its edges into the usual lock-seam ready for soldering; also, to provide a machine which will produce two or more canbodies ata time, and thus practically double, treble, or quadruple the capacity of the machine without materiallyincreasingits cost.

The invention consists, in connection with a ean-body-making mechanism, of a'blankfeed device for automatically feeding the blanks one by one from a pile to the machine.

It also consists, in the combination, with a single horn around which the can-bodies are formed, of a multiplex can body-forming mechanism or device adapted to operate upon two or more blanks at once, whereby two or more can-bodies may be produced simultaneously.

It also consists, in connection with such horn. and multiplex ean-body-'forming mechanism, of a single extractor device for pushing the can-bodies simultaneously off the horn.

It also consists in the novel devicesand novel combinations of parts and devicesherein shown and described, and more particularly pointed outin the claims.

In the accompanying drawings, which form 4o' a part of this specification, and in which similar letters of reference indicate like parts, Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a plan view. Fig. 3 is an end view. Fig. eis au enlarged section on line i el of Fig. 1. Fig. 5 is an enlarged detail vertical sectional view, showing the blank-holder, blank-feed mechanism, and mechanism for forming the rst fold or hook on the forward end of the blank. Fig. 6 shows the hook forming or folding Serial No. 304,237. (No model.,`

mechanism of Fig. 5 in a different position. Fig. 7 is a longitudinal section of the hornshaft. Figs. 8 and 9 are enlarged detail crosssectional views of the driving-shaft and hornshaft, showing the mechanism for operating the horn-shaft. Figs. 10, 11, 12, and 13 are detail cross-sectional views of the horn, showing the mechanism in different positions as performing the successive operations upon the blank. Fig. 14 is a cross-section of the 6o horn taken on line 14 14 of Fig. 2, and showing the mechanism for operating the bumper or seam-squeezing device. Fig. 15 is a detail perspective view of the blank-holder; and Fig. 16 is a detail sectional view of the blank- 65 feed device. Figs. 17, 18, 19, and 2O show the sheet or blank in successive stages or steps of operation performed upon it by the lnachine, Fig. 17 showing the blank with the iirst hook or fold formed upon one end, Fig. 18 7c showing the blank with the second hook or fold formed upon its opposite end, Fig. 19

showing the blank formed or curved into cylindrical shape and the two hooks interlocked, and Fig. 2O showing the interlocked hooks 75 pressed or squeezed into the seam. Fig. 21 is a detail view of the horn-support. Figs. 22, 23, and 21 are detail views of cams for operating certain parts described.

In my invention the blank is first auto- 8o matically fed from a pile or stack of blanks X to a suitable edge-folding mechanism or device, which forms the 'first hook upon one end or side of the sheet. The blank is next automatically fed or conveyed to the edgefolding mechanism or device which forms the second hook or fold m2 upon its opposite end or side. This second edge-folding device is preferably mounted in or upon the horn around and upon which the can body is 9o formed, so that this second edge-folding mechanism, which grasps the blank to make the second hook 502, may be utilized or serve also as the means for clamping the blank to the horn. The blank is next by the rotation of the horn wrapped around the horn and the iirst hook or fold imposed or hooked over the second one, interlocking the two together. The next operation is to bump, squeeze, or compress the interlocked hooks or folds roo against the horn, and then the can-body or can-bodies are extracted or pushedoff thehorn by a suitable extractor device.

In order to form two can-bodies at a time by the same mechanism, the first edge-folding device, as well as the second edge-folding device and horn, is made long enough to operate upon two blanks at a time, separate guides, passages, or chutes being provided for the two separate blanks.

To enable the machine to operate upon four can-body blanks at a time, the edge-folding devices and bumping or squeezing device are duplicated at the opposite end of the horn.

In the drawings I have shown that form of edge-folding or hook-making mechanisms, horn-bumping or seam-squeezing device, and blank-feed device which I prefer to use and to combine together for practicing my invention; but the construction of each of these several devices may be greatly varied by those skilled in the artwithout departing from the principle of my invention and the broader features thereof.

In the drawings, A represents the frame of the machine. This may be of any suitable construction to give support or bearing to the several operative devices or parts of the machine. p

B is the blank-holder, secured to the frame of themachine, and by which the pile or stock of blanks X is supported. This can-body blank holder preferably consists of an inclined bottomless box having a projecting lip b at its lower edge, upon which one edge of a pile of blanks X rests, and a ledge b upon which the other end of the blanks res ts. The blankholder B is also preferably furnished with one or more-preferably two-slotted arms b2, pivoted at b3 to the frame and mounted in suitable slots b4 in the ledge b', and which are pressed up against the pile of blanks X at the end thereof by springs b5. The slot t6 in these arms b2 is just wide enough to admit one sheet or blank, so that only the lowermost blank of the pile can be pushed endwise into this slot, so that its forward end will free the shoulder or projection b. This slotted arm lf2 is used as a safeguard to prevent possibility of feeding two or more blanks at a time from the pile. This slotted safeguard b2 is preferably mounted in a pivotal or yielding manner to insure its being in proper position against the end of the pile of blanks. The forward end bl of the slotted safeguard or arm b2 is made tapering, as indicated in Fig. 5, so that this tapering portion may project slightly under the pile of blanks, and thus better guide the lowermost blank into the slot h.

C is the automatic feed device by which the blanks are fed or delivered one by one. from the pile X. This feed device O may be of any suitable construction adapted to feed the blanks one by one from the pile; but as sheets of -tin vary somewhat in thickness, the blank feed device which I prefer to employ is one which I have -specifically devised for use in combination with the other operative parts of my machine. This preferred form of feed device consists in a pair of opposing blades C C, (see Fig. 16,) having knife-edges inclined to the plane of the sheet, so that when pressed up against the bottom of the pile of sheets the knife-edges of the blades C O will only engage the opposite edges of the lowermost sheet. The feeder of course preferably consists of two opposing blades; but if only one blade is employed it will sufliciently engage the lowermost sheet to pull it back over the ledge l). The feeder-blades C are secured to or made integral with a slide C', by which they are moved or reciprocated sufficiently to pull or push the lowermost blank over the ledge b and permit its forward edge or end to movedown between the edge-folding device D and the dies or jaws D D2, which oppose the hook-forming or edge-folding device D. The feeder-slide C reciprocates on a swing ing arm or frame C2, which is pivoted to the frame at C3, in order that it may swing out of the way of the blank, and thus pei-init the rear end of the blank to swing down into position to be received by the second edgc-folding or hook-forming device F, which is carried by the horn G. The swinging or pivotal movement of the blank about the edge-folding or hookforming device D thus reverses or turns the blank end for end before it is delivered to the second hook-forming device F.

extending between the hook-forming devices D and F.

The pivotal arm Cgis furnished with an eX- tension Ct, extending down neary thev end of the blank, to support the blank and prevent it from bending. After the feed device C moves backward to push the lowermost blank back sufficiently to permitits loweror forward end to drop over the supporting-ledge b of the blank-holder, the pivoted arm or frame C2 is caused to swing down slightly to release the pressure of the feeder-blades C C against thel pile of blanks, and thus permit the now freed lowermost blank to slip down by its own gravity to the hook-former or edge-folder D.

I prefer to so arrange the blank-holder B and feed device F, as well as the blank-passage E, on an incline to the horizontal that the gravity of the blanks may be utilized to cause the blanks to move forward to thehookformers or edge-folders D and F. It is obvious, however, that they may be differently arranged, and suitable means other than the gravity of the blanks employed to push the blanks forward to the edge-folders D and F. I prefer, in order to utilize the gravity of the blank for the purpose of reversing or turn ing the blank end forend about the lirst hookformer D as a pivot, to-arrange the blankholder B and the passageE at an angle to each other, about as shown in the drawings; but my invention is not limited to this construction or IOO arrangement wherein the gravity of the blank is made to aid in reversing or turning the blank end for end.

The hook-formeror edgefolderD has a web or blade-like projection d, over which the fold or hook 5c is formed. The former D is pivoted at d to a rotary shaft or head DS, jour naled upon the frame of the machine. The die or jaw D is secured rigidly to this rotary head, and the die or jaw D2 is secured to the rigid frame-work of the machine. This die is preferably, in fact, made integral with the end piece of the blank-holder, against which the forward end of the pile of blanks abuts'. The hook-former D is given a vibratory movement on its pivot d by means of a camshaped lever cl2, pivoted at cl3 to the rotary head D3, and which engages a stationary cam D, secured to the frame of the machine. As the head D3 rotates, the cam-lever d2 engages a wing or arm d, secured rigidly to the former D, which gives theformer D its closing movenient against the opposing dies D D2, as clearly shown in Figs. 5 and 6. The former D is swung back or opened to release the hook m that has been formed, and to receive the succeeding blank, by a pin d5, mounted in a suitable slot or hole in the rotary head D3, which pin is engaged by the cam-lever cl2. The simple rotary or oscillatory movement of the head D3 thus forms the first hook or edge fold as upon the forward end of the blank no.

In Fig. 5 the dotted line l represents the blank after it has fed down against the rotary die D', which acts as a stop for the sheet. lf the blank should drop down against and rest upon the side face CP1 of the die D', as may sometimes happen, when the head D3 rotates slightly from the position ,shown in Fig. 5 in the direction shown by the arrow, the blank :1:4 will slip off the side face of the die D and restupon the end face of said die, as shown by dotted line in Fig. 5. The movement of the former D on the head D3, to which it is pivoted, will next clamp the end of the sheet or blank between the endV face of the die D and the adjacent face of the web or blade d. The farther rotation of the head D3 into the position shown in Fig. 6 completes the hook by carrying the blank against the stationary die or jaw D2. As shown in Fig. 6, the dies D and D2 constitute a female die, into which the edge of the sheet is pressed by the web or blade d on the formerD. The backward movement or rotation of the head D3 now opens the former D and swings the blank a3 down about the head D3 as a pivot, so that the rear end of the bla-nk will be fed foremost to the horn G and edge-folder F carried thereby. The edge-folder F has a lip or blade f, which operates to clamp the edge of the sheet against the opposing die or jaw F, which is or should be correspondingly recessed. The former F is pivotedl at f to the horn G, and it is operated by a sliding wedge or bar (,which, like the former F, is mounted in asuitablc recess g in the horn G. The

horn G is mounted in suitable bearings Glon the frame of the machine, and is given a rotary movement in the direction indicated by the arrows in Figs. l0, 1l, and l2, which rotary movement serves, after the end of the sheet is clamped between the former 'F and die F', to Wrap the blank or sheet around the horn, and thus form or shape up the can-body. In Fig. 10 the blank is shown fed down in position for its end to be clamped between 'the now open former F and the die F. In Fig. 1l the same parts are shown with the former F closed and clamping the edge of the blank between itself and die F. The rotation of the horn G in the direction indicated by the arrows in Figs. 10 and l1 now wraps the blank around t-,hc horn and at the same time completes the formation of the second hook or edge fold at?. The act of wrapping the sheet or blank around the horn folds the same over the lip f of the former F. The guides or shoes H2 K L surrounding the horn serve to hold and bend the blank around the horn as the horn is rotated, one edge of the blank being clamped between the dies. This function may also be in part performed by the presser P, as will be clearly understood from Figs. l0 and 1l. The horn makes somewhat more than a complete revolution into the position shown in Fig. 12.

H is a stop-blade, which engages the lirst hook or edge fold x as the blank is being wrapped around the horn by the rotation thereof. This stopbladeis arranged near the periphery of the horn, so that it will surely engage the first hook or fold and hold it in position for interlocking with the second hook or fold @c2 of the blank, as shown in Fig. l2. The stop-blade H is preferably mounted movably, so that it may be moved toward or from the horn, as desired. I prefer to mount this stop-blade on an arm or lever H', pivoted at h to the frame of the machine, so that it may be swung to or from the horn. The arm H also preferably carries a curved shoe or presser device H2, which may be made integral with the stop-blade H or the pivoted arm H. The arc of this shoe should correspond with that of the horn. The purpose of this shoe is to press the inner end of the blank a', which carries the first and now outwardlyprojecting hook x', liat against the horn during the operation of interlocking the second and now inwardly-projecting hook x2 with the first hook at', said second hook hooking over the first hook as is clearly indicated in Fig. l2.

The horn Gbeing a solid one, as contradis tinguished from an expansible or compressible one, is made smaller than the iinished ICS IlO

can-body, so as to permit the overlapping of of the hooks x2 a second guide-shoe K is provided,rwhich, like the shoe H2, is preferably made movable, so that it may operate to press the blank more snugly against the peripher'y of the horn and cause the lap or excess portion of the can-body to continue around the horn to the part where it is needed to permit or cause the hook Q32 to overlap or hook over the hook 0c', as is indicated in Fig. 12. This guide-shoe K is preferably7 mounted upon or secured to the end of a lever K', pivoted at 7c to the frame of the machine. A third guide-shoe L is located farther around the horn, the same being preferably secured rigidly to the frame of the machine. This third guide-shoe is designed simply to preserve the cylindrical shape of the can-body after the former F opens and releases the hook .-002 preparatory to the interlocking or overlapping of the hooks 002 It lits the horn somewhat loosely, but is provided with a cam-like projection L', which serves to keep the blank close to the horn. This will be clearly understood from Figs. 4 and 12. After the horn G revolves around nearly to the position indicated in Fig. 12, the former F is opened, thus releasing the hook x2, and the movable guide-shoes II2 and K being'then pressed up against the horn, the hook m2 is lapped over or carried beyond the hook Qc', and while the blank and horn are in this position the bumper or seam-squeezing device P, which carries a movable blade or projection p, moves or swings up into the position indicated in Fig. l2 and crowds or pushes the fold or hook x2 into the hook This is clearly indicated in Fig. 12. The horn G now rotates backward vto the position indicated in Fig. 13, thus bumping or squeezing the interlocked folds or hooks an ce2 into a solid seam. The movable blade or projection p slides on the bumper P, so that its face shuts in flush with the operative face of the bumper. The seam-squeezer or bumper P is preferably pivoted to the frame at p, and it is furnished with an operating-arm P4, actuated in any suitable manner. The bladel p of the presser P is mounted in a suitable slot or way in the presser P, the blade itself being also slotted to limit its outward movement, as is clearly shown in Figs. 12 and 13. The blade moves outward by its own gravity and is pushed back by contact with the horn. It may, however, be moved by any suitable means.

The passage or chute E, as shown in the drawings, is sufficiently inclined to permit or cause the blanks to slide down tothe former F and horn G by their wn gravity; but I prefer to provide a positive device for moving the sheets along this passage E to the former F. This feed-pusher device may preferably`consist of a simple feed-lever Q, pivoted at q to the frame and actuated by any suitable means.

To properly support the horn against the thrust of the plunger or squeezer during the squeezing operation, I provide at each end of the horn a support S, which is preferably secured at s on the'frame ofthe machine diametrically opposite the pivot p of the plunger P. This horn-support S is made slightly tapering to permit the can-bodies to enter between the horn and support, (see Fig. 21,) and it is located the full thickness of the blank away from the horn to permit the free extraction of the can-body after the seam is closed. The slight spring of the horn brings it against the support to resist the thrust of the squeezing mechanism. By the backward rotation of the horn before referred to, a tooth or projection p2 on the operating-arm P of the seam-squeezcrP engages a similar groove or recess p3 in the horn G, and thus insures the opposing action of the support S to the v thrust or pressure of the squeezer P.

T is the extractor or device which pushes the finished can-bodies from the horn. the slide T, to which it is attached, reciprocates in suitable guides T2 on the frame of the machine.

The blank-holder B, the feed device C, and the chute or passage E are duplicated on each side of the machine, there being four of-each in the machine shown in the drawings, these parts being separate for each can-body blank; but the edge-folders or hook-formers D and F, horn G, stop-blade H, guide-shoes H2, K,

It or and L, bumper or squeezer P, blank-pusher Q, and extractor T are combined and ar-` ranged to operate upon two can-bodies orcanbody blanks at a time, the edge-folders, dto., being simply made long enough to operate upon two can-bodies inst-cad of one. It will thus be seen that by very little additional expense in the construction of my improved machine it may be made to make two canbodies at a time on each side.

It should be understood that while one feature of my invention consists in the means I employ to make two or more can-bodies simultaneously, other features of my invention are not coniined to this double-acting construction.

It should also be understood that the edgefolders D and F and other parts may operate upon three or more adjacent blanks or canbodies at a time instead of two, as shown in the drawings.

I have now described one end or half of the machine which serves to make two can-bodies at a time, and as the other end or half of the machine is an exact duplicate of the end or half already described, it is of course not necessary to duplicate the description.

In Fig. 1 of the drawings the duplicate mechanism at the left hand of the machine is indicated, some of the parts, however, being IOO IIC

omitted or broken away to better show parts that would otherwise be concealed.

The operating mechanism or lneans for communicating to the several operative parts their required movements, as before described, may of course be greatly varied by the skilled-mechanic. The required movements may be communicated to the several operating parts or devices by any suitable means desired, and I desire it to be understood that my invention is not limited to any particular means or mechanism for communicating tothe operating parts their movements.

In the drawings I have shown a suitable form of operating mechanism for communieating to the various parts before described their movements, and I will now proceed to describe these operatin g or motion-producing devices.

The feed-slide C', which carries the feed device C, is reciprocated on the swinging guide-arm C2 by means of a cam c2, Fig. 22, on the main driving-shaft R, through a link c3, connected with the arm c4 of a rock-shaft c5, having an arm c6, connected by a link c7 with the feeder-slide C.

The swinging guide-arm C2 is rotated or swung about its pivot C2 by means of a cam c on the main driving-shaft R, through a lever G10 and link C11, connected to the crankarm c12, secured to the pivot or rock-shaft C2.

The rotary head or shaft D2, which carries the hook-former D and die D, is operated by means of a cam C17, Fig. 23, on the main driving-shaft R, through the lever d8, connectinglink (i211, and crank-arm d10, secured to said rotary head or shaft D2.

The means for operatin g the hook-former D by the rotation of the head D2 has already been described.

The former F, which is carried by the horn G, is operated by the wedge g, as before described, by means of a sliding key g1, mounted in a groove g5 in the shaft G of the horn G, and connected with the wedge g by a projection gs, iitting in a slot or hole in the wedge g, and connected to a sliding collar or sleeve g7 by a projection g8, fitting in an annular groove g in said sleeve. The sleeve g7 is reciprocated as required to move the wedge g by means of a cam Q10 on Vthe main drivingshaft R, and a lever g11 connected to said sleeve Q7.

The horn G or its shaft G is given its forward rotation to wrap the blankx around the horn by means of cams G2 G3 on the main driving-shaft R, through the bent lever G4, pivoted at G5 to the frame, connecting-link G15,

- segment-gear G7, and gear G8 on the shaft G',

and the horn is given its backward rotation, as before described,by means of cams G9 G10 on the main driving-shaft, pivoted guide-arm G11, connecting-link G12, lever G13, connecting-link G11, and crank-arm G15, secured to the sleeve or collar G16 on the shaft G. The shaft G is alternately fixed to the sleeve G1 and to the gear G8 by means of a sliding key.

I `prefer to utilize for this purpose the same sliding key g1 which is used to operate the wedge g, though a separate key may of course be employed. A

The stop-blade II and guide-shoe H2, which are carried by the pivoted arm H', are operated by a cam h' on the main driving-shaft R through the lever h2, pivoted at h3 lto the frame and connected by a link h4 to the movable arm II.

The guide-shoe K,`carried by the lever K',

is operated by a cam 7c on the main drivingshaft R.

The bumper or seam-squeezing device P is swung or rotated on its rock-shaft or pivot p by means of a cam P2, Fig. 24, on the main driving-shaft R through a lever P2 and connecting-link P1, pivoted to the operating-arm P', which is secured to the shaft p. This cam P2 and connecting mechanism are preferably simply used to throw the tooth or projection p2 into and out of engagement With the recess 132 in the horn, the rotation of the horn then serving to further rotate the squeezer P into the line joining the axes of the horn and shaft 1J. A spring P5 holds the operating-arm P in position for the tooth p2 to engage the recess p2 in the horn.

The blank pusher' or feeder Q, is operated by a cam Q' on the main driving-shaft R. A spring Q2, mounted on the middle or dividing rib or bar of the feed-chute E, serves to rctract the feeder Q.

The can-body extractor T or its slide T vis operated by a cam T2O on the main drivingshaft through the lever T2, rock-shaft T4, lever T5, connecting-link TG, lever T7, and link T2, which is pivoted to said slide T.
